Madhulika “Maddie” Vishwanathan is an associate in Sterne Kessler’s Biotechnology & Chemical Practice Group. Maddie’s technical expertise includes small molecule drugs, pharmaceutical formulations, pharmacokinetics, specialty chemicals, phytochemicals, water treatment, paper treatment chemicals and agrochemicals.

Prior to attending law school, Maddie worked as an in-house technical assistant in the legal department of an international specialty chemical company in Memphis, Tennessee for about 3 years where she helped manage global patent portfolio in the areas of specialty chemicals, pesticides, polymers, water treatment chemicals, novel chemical formulations, enzymes & chemicals used in papermaking. She assisted in several prior art search and analysis, patentability assessments, patent validity assessments and strategic analysis of competitors' technologies and patents. She actively collaborated with internal R&D and outside counsel on matters of patent drafting, legal research and designing strategies around non-infringement. She performed patent portfolio due diligence and counseled upper management regarding M&A opportunities.

Prior to this role, she worked as an intellectual property specialist at a law firm in downtown Memphis where she worked with independent inventors and university technology transfer offices to identify inventive concepts for coverage in patent applications. She worked on a wide array of patent matters related to technologies such as biodegradable nanoparticles for ophthalmic applications, synergistic combinations of pesticides and a synthesis of a novel phytochemical active.

Before her law firm experience, she worked at a large India-based generic biopharmaceutical company. As an executive in the in-house IPR department, she gained extensive experience in matters related to Hatch Waxman, prosecution, patent drafting and litigation support. She helped manage patent landscaping for generic and proprietary drugs (small molecules) and assisted in performing infringement analysis of products for multiple markets. She assisted in drafting U.S. and PCT patent applications while also performing freedom to operate and non-infringement opinions for Paragraph IV ANDA filings. She also helped identify opportunities for first-to-file and sensitized management on current FDA Orange Book patent listings.

As an IP blogger for SpicyIP, a leading IP blog, she dissected publicly available complex patent rulings and court orders and explained them to the general public.

Maddie received her J.D. from the Mitchell Hamline School of Law where she earned a CALI award for patent prosecution. She received a B.S. in Pharmaceutical Sciences from the University of Mumbai and an M.S. in Pharmaceutical Sciences from the Institute of Chemical Technology. Maddie’s dissertation research relates to isolation of phytochemicals and evaluating hepatoregenerative effect of phytochemicals after inducing oxidative stress using acetaminophen in Albino Wistar rats.
